<span>The best property for ionic bonds is its conductivity of electricity when molten. An experiment that can be recalled on this is the NaCl in water that is used to light up a bulb. Ionic compounds are highly soluble in water when dissociates. They also have high boiling points because of the ions integrated. </span>
Answer:
It is true that earth was once covered with oceans and little dry land.
Explanation:
Over the course of around four billion years, the Earth's oceans have lost about a quarter of their original mass. Today the atmosphere is rich in oxygen, which reacts with both hydrogen and deuterium to recreate water, which falls back to the Earth's surface. So the vast bulk of the water on Earth is held in a closed system that prevents the planet from gradually drying out. According to the researchers, the continents emerged relatively suddenly from an ocean that covered 95 percent of the Earth's surface. The appearance of large masses of dry land would have caused more extreme weather, changes in ocean currents and the emergence of proper seasons. In turn, these environmental changes may have led to rise in atmospheric oxygen that enabled the explosion of new life forms around 500 million years ago.
Potassium acid phthalate will serve as our primary standard. This is a large molecule (KHC8H4O4) with a molar mass of 204.2 g/mol. Instead of writing the whole formula, we abbreviate it as KHP, where "P" stands for the phthalate ion, C8H4O42-, not for phosphorus. KHP is an acidic substance, with the ionizing hydrogen being set forward in the formula for emphasis. Therefore, KHP is monoprotic and will react with NaOH in a simple 1 to 1 relationship according to the following equation:
Answer:
A study performed by Dr. Birdie signified that the number of songbirds in her yard enhanced because of a modified source of food.
Explanation:
A scientific claim refers to a claim, which is postulated by a scientist because of the outcome, which he or she has attained in the research that has been conducted. In the given case, it can be witnessed that Dr. Birdie experience influx of songbirds to her yard as an outcome of the dried apple and the raisin, which she has supplemented in the diet of the birds.
Answer:
3.122 kg/L.
Explanation:
Density = mass / volume
Density = 2.56/ 0.82 = 3.122 kg/L.
